Noise and Impedance Effects
To minimize noise pickup or radiation, use shielded pair wiring of the
shortest possible length for load wires. Connect the shield to the chassis
via a rear panel mounting screw. Where shielding is impossible or
impractical, simply twisting the wires together will offer some noise
immunity. When using local sense connections, use the largest practical
wire size to minimize the effects of load line impedance on the regulation
of the supply.
Making Load Connections
Make load connections at the rear of the power supply at the positive and
negative output bus bars or to the 4-terminal wire clamp connector,
depending on the model.
Output Cover
The power supply comes with a bus bar cover and strain relief. See
Figure 2-4. This cover is also installed on models fitted with the high
voltage output connector.
To detach the 2-part cover:
1. Undo 6-32 x 5/16 in. Phillips pan head screws, 6 x 0.288 in. lock
washers, and 6 x 5/16 in. flat washers (3 places) from the top cover.
2. Pull up on the top cover to remove it.
3. Undo 6-32 x 1/4 in. Keps nuts and 6 x 5/16 in. flat washers from the
chassis-mounted PEM studs (3 places) to remove the chassis cover.
CAUTION
When making connections to the bus bars, ensure that each terminal's mounting
hardware and wiring assembly are placed to avoid touching the other terminal
and shorting the power supply output. Heavy connecting cables must have some
form of strain relief to avoid loosening the connections or bending the bus bars.
